  1. Report from TTC Milanohttp://agenda.infn.it/conferenceOtherViews.py?view=standard&confId=3087 W. Weingarten / CERN SPL cavity working group 7 March 2011 SPL cavity WG

  2. Introduction and Update since Last Meeting Yoshishige Yamazaki TTC Chair J-PARC, KEK & JAEATESLA Technology Collaboration (TTC): • In contrast to its formal looking from outside, the collaboration and its meeting are very much scientific and technical rather than political, having very frank, active discussion. • The most important mission of the collaboration is to provide highly scientific, technological reports, responding to requests from the member institutes. • I proposed to invite the proton community like SNS and heavy ion one to TTC, since I have been working for the J-PARC proton linac, which will have SC linac in future

  3.

  7. Civil Construction TTC Meeting, Milano, February 28 to March 3, 2011 Hans Weise, DESY

  8. RF Measurement and Field Flatness Tuning using DESY-provided Tools • Both machines ready to be used at the companies (CE certified). • Machines can be operated basically by Non-RF-Experts. • Considerably shorter measurement / tuning time. • Automation and documentation guaranteed. TTC Meeting, Milano, February 28 to March 3, 2011 Hans Weise, DESY

  9. Cavity Surface Treatment – Based on DESY Experience • Two schemes for the final surface treatment (Final EP and BCP Flash) were studied with cavities from two different vendors. • The preparation strategy to go for a final treatment with the cavity already welded into the He-vessel was investigated. • Results are: - yield curves for the different schemes - yield curves for the different vendors - a preparation strategy allowing two different final treatments • Some tooling will come from DESY • DESY procedures and experience described very much in detail in the CFT • Specification are now available to the SRF community since end of 1/2011.
